I seem to remember that it could be 9 or 10 depending on man. date. I don't remember any more than that it has been 22 years ago that I sold the jubilee. As Big Boy said pull it down and see. Also don't be tempted to just replace the disk, replace it all, disk barring and p plate It is too much work to try to get by.

Well, I got the Jubilee split in half tonight and clutch was a 9" and it had the older bushing style - Unfortunately , the bushing got pushed forward somehow and the driveshaft wore the bushing hole way too big for a replacement bushing... I guess I am going to try to find a newer style Flywheel that will accept the newer bearing. ( unless you guys have another suggestion ? ) Tranny seal was definitely leaking as well and splashing oil up on the clutch. Posted some pics below of the process so far..
